Description
Technical field
The present invention relates to dyke flood-fighting technical field, specifically a kind of novel implanted relief well is depressured drainage system
And method, especially suitable for being applied when flood season piping dangerous situation emergency repair.
Background technique
The binary structural stratum of upper layer clay, lower coarse fine sand, the infiltration of upper layer clay is presented in the most of levee foundation grounds in China
Property it is poor generally 10-5~10-7Cm/s, the sandy soils permeability that underlies is stronger, and generally 10-2~10-4Cm/s, high underground water
When stratum easily show artesian condition.Flood season meet water side river level rises sharply in the case where, since layer of sand permeability is strong,
River is leaked by layer of sand underground water into dike, punctures coating easily in the weaker position artesian water of clay layer, is generated
Piping dangerous situation.Relief well is as a kind of drainage pressure-reducing measure, because it depressurizes theoretical maturation, construction is simple, effect obviously etc., in dike
Extensive use is received in preventing engineering.The double-deck pressure reducing well pipe device for osmotic control, prevent sand boil or piping have it is significant
Effect.In China, since the 1950s, the infiltration control that it is used as a kind of processing pervious levee foundation Seepage problems is arranged
It applies.But there are following points for the construction of conventional pressure relief well flood season.
1, conventional pressure relief well is using first drilling and placing well casing mode pore-forming Cheng Jing, if flood season construction drill punctures clay layer
It is more also easy to produce sand boiling afterwards and gushes the new dangerous situation such as sand.
2, conventional pressure relief well construction is complicated, need to pass through drilling, down tube, backfill filter material, backfill clay, well-flushing, newly-built row
The processes such as ditch, it is slow for emergency handling reaction speed.
3, do not consider reverse filter effect, be implanted directly into the permeable floral tube of stainless steel when tube wall water-permeable pipe penetrates clay layer, floral tube
Hole wall adhesion clay blocks hole wall, is unfavorable for pore water discharge.
4, relief well engineering is the flood control installation for flood season high water level drainage pressure-reducing, and conventional pressure relief well is mostly applied in dry season
Work, according only to former years dangerous situation, creating relief well improves dyke drainage pressure-reducing condition in gang of wells place.In no flood situation, play
Not Benefit of Flood Preventation, causes engineering construction waste and managing redundant.
Summary of the invention
The technical problem to be solved by the present invention is to overcome above-mentioned the deficiencies in the prior art, break through conventional pressure relief well construction method
The qualitative thinking of dike not drilling well close with flood season dyke provides a kind of novel implanted relief well decompression drainage system and method, in flood
Phase improves stratum drainage condition, cuts down levee foundation soil body water pressure, safeguards Seawall safety.

1) according to the practical clay layer of engineering, layer of sand feature (the stringent diadactic structure in stratum is distributed clay thickness 6m in this example,
The super 9m of sand thickness) it prepares stainless steel reality steel pipe (outer well tube 1), the permeable floral tube of stainless steel (interior well casing 2) and is assembled into bilayer and subtracts
Kill-job pipe device: outer well tube 1 is 6m long, and single 3m is connected by trapezoidal thread, diameter 75mm, wall thickness 5mm；Interior well casing 2 is single
Long 3m can be lengthened by being gradually implanted into 9m, diameter 45mm, interior well casing tube wall open pore size 4mm, and water permeable area 15% is located at
Well casing solid core undergauge section 33 (such as Fig. 2) and the cone that breaks ground in interior 2 lower end of well casing welding, 30 degree of coning angle；Interior outer well tube passes through Z
Shape slot 3 and the formation of column bayonet 12 snap connection, and such overall package is at the double-deck pressure reducing well pipe device, the interior well casing 2
Bottom is welded with the cone 11 that breaks ground.
2) the double-deck pressure reducing well pipe device implantation position is selected, sets the above-mentioned double-deck pressure reducing well pipe dress in construction point vertical rack
It sets, fixing device for installing and hammering implantation power device are implanted into power device for the double-deck pressure reducing well pipe by hammering using external force
Device clay section outer well tube (containing interior well casing) is rammed into the soil body, covering layer soil body (about 6m) is penetrated, specifically, using air compressor machine
Using so that the double-deck pressure reducing well pipe device soil compaction enters the soil body and penetrates coating for 21 power cooperation hammer 22, is then turned off
The connecting tube of air compressor machine and hammer 22.
3) bull stick 29 of rotating mechanism 30 is inserted into the cross recess 26 of interior well casing rotation pipe 20 by well casing rotating device in installing
In, rotation rotating mechanism drives interior well casing 2 to rotate, and lateral rotation is certain in translot 13 on Z-shaped slot for interior well casing cylindricality bayonet 12
After distance, interior well casing 2 is hammered downwards, cylindricality bayonet is made to move down straight Z-shaped slot lower part in vertical slot 14, rotation rotation again
Mechanism 30 makes cylindricality bayonet 12 after lower translot 15 moves a certain distance, and hammers interior well casing 2 and interior outer well tube is separated, separation
The fixation of outer well tube 1 afterwards continues to be fixed in clay layer, removes interior well casing rotation pipe 20 after separation, in interior 2 upper end of well casing setting
External screw thread 25 (as shown in Figure 10) is arranged in interior 32 bottom end of well casing extension pipe in screw thread 24, reconnects interior 32 He of well casing extension pipe
Hammer 22, air compressor machine 21 and connecting tube 23 squeeze into interior well casing 2 in sand through hammering implantation by 21 power of air compressor machine
Interior well casing 2 is rammed into layer of sand by power device.
Wherein, interior well casing 2 continues soil compaction vertically downward and is detached from outer well tube 1 after separating with outer well tube 1,.
